The OP refers to <up> and <down>.  In the minibuffer, these keys by
default navigate so-called "minibuffer history", where e.g. <down>
inserts "future" history, AKA the next default value.  So <down> is
actually "navigating" the list of defaults (completing-read's 7th
argument), not the list of completions (completing-read's 2nd argument).

If this is not the kind of input you're referring to, then could you
please clarify which input you're referring to?
